The Apera PH60S (AI313) is a professional handheld pH meter designed for direct testing of solid and semi-solid growing media, including coco coir, rockwool, and living soil. Its Swiss-made LabSen 753 spear electrode penetrates substrates without requiring slurry preparation and can also test standard nutrient solutions. The replaceable double-junction electrode provides stable readings, while the IP67-rated meter is suitable for humid commercial cultivation environments.
